Evaluating Self Hosted Authentication Options for Compliance
Does anyone here have recent experience migrating to self hosted multi factor authentication due to strict data residency laws? I am looking for rational insights into how difficult the infrastructure maintenance actually is compared to the cloud alternatives.

When evaluating authentication architecture for environments under GDPR or NIS2 compliance the cloud approach introduces too many variables. Maintaining data control is easier when authentication packets never leave the internal network. For organizations handling sensitive infrastructure or cardholder data keeping everything local eliminates third party risks. I found detailed technical breakdowns regarding compliance and deployment models at https://www.protectimus.com/on-prem-mfa/ which helped clarify how isolated networks handle token validation. A self hosted platform definitely requires more internal resources and maintenance than a cloud service. However avoiding the uncomfortable questions from auditors about where the data actually lives makes the infrastructure overhead a logical trade off. It is mostly a matter of choosing between operational convenience and total control over data residency.
